WHEELWRIGHT-MACHINE.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed June 5, 1906. Serial No- 320,331.

To all whom it may concern:

Be it known that 1, JAMES M. ROBBINS, a citizen of the United States,residing at Rochelle, in the county of McOulloch, State of Texas, haveinvented certain new and useful Improvements in Wheelwright-Machines;and I do hereby declare the following to be I a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to wheelwright machines, the object thereof, ingeneral, being to provide a simple, inexpensive, durable and efiicienthand-operated machine embodying means for drilling the telly and tire ofa vehicle wheel for the reception of the tire retaining bolts. v

The particular improvements consist in the construction of a machine ofthe above mentioned type, comprising a pair of sections detachablyconnected together, the front section carrying a pair of pliers mountedin a pair of ears pivotally connected with the outer end thereof, tograsp the wheel rim and move the entire machine forwardly, thusadvancing the drill or bolt wrench carried by the rear section.

Further improvements consist in the construction of the rear section insuch manner that it may be readily detached from the front section andoperated singly as a breast drill or bolter. I

With these and other objects in view, the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size and minor details may be made, within thescope of the claims, Without departing from the spirit or sacrificingany of the advantages of the invention.

In the drawings:Figure 1 is a side view of my invention. Fig. 2 is aplan view illustrating its application to a wheel. Fig. 3 is a detailview of the spoke engaging member. Fig. 4 is a detail view of the pliersillustrating upon an enlarged scale its mounting with respect to theframe. Fig. 5 is a detail view of the machine converted into a breastdrill.

Referring to the drawings, 10 and 11 designate respectively, the frontand rear sections of the machine, detachably connected by a bolt 12, asshown in Fig. 1, the front section being formed with an integralinwardly extending flange or shoulder 13, at its inner end, upon whichthe rear section rests and is more completely held in place. Saidsections are provided, respectively, with downward extensions 14 and 15,the former having pivotally connected thereto, at its lower end, a pairof ears 16, in which is secured by a pivot-pin 17, the upper member 18of a pair of pliers. The jaw and handle of said member 18 areapproximately in direct line with each other, while the inner end of thelower member 19 is bentupwardly and then inwardly, at right angles toits upward bend, as shown in Fig. 4. The pivot bolt 20, of said members,is located at the rear of ears 16.

The depending extension 15 of the rear section 11 is provided adjacentits lower end with an opening, in which is rotatably mounted a drillshank 21, said drill shank carrying on one end a sleeve rigidlyconnected thereto and formed with an integral bevel gear 22. On itsopposite end said drill shank carries a spoke-engaging member 23 looselysurrounding the same and held in place thereon by a bolt or pin. Themember 23 has curved portions projecting on each side of the shank 21,as shown, and is of sufficient length to engage a pair of wheel spokes.

To rotate the drill shank, a vertical shaft 24 is mounted in the rearsection 11, and carries at its lower end a beveled gear 25, meshing withthe gear 22 on said shank, a crank handle 26 being provided at the upperend of said shaft. The front section 10 carries a vertical brace 27,extending on opposite sides thereof, and bolted thereto, as shown, saidbrace being provided with broadened and flattened ends 28, designed toengage the wheel rim directly over the part thereof through which thebolt hole is to be drilled. The drill shank is provided with the usualsocket 29 for a drill or bolt wrench.

In the operation of the machine, the wheel to be drilled is firmlyattached to its bench, and the machine then placed in position thereon,with its spoke-engaging member in place beneath a pair of spokes, asshown in Fig. 2, the flattened ends of brace 27 being directly over thepart through which the bolt hole is to be drilled. The shaft 24 is thenrotated, driving the drill shank, and starting the hole in the wheelrim. As the bit feeds into the folly in forming its bore the machine isnecessarily moved therewith, and in such movement the member 23 and thebrace 27 slide over the surface of the parts upon which they bear, thusconstituting guides for the machine in its movement due to the action ofthe bit. As the machine is thus advanced, the pliers, owing to theirpivotal suspension from the ears 16 and owing to the from the ears 14,may be kept in engagement with the felly, the double pivotal suspensionabove noted thus compensating for the movement of the machine with thebit. The jaw of the upper plier member 18 is formed with a slight upwardbend at its outer end to enable it to more firmly clamp the wheel rim.

To convert the machine into a breast drill, as shown in Fig. 5, it isonly necessary to remove the front section 10, and to the rear end ofthe shank attach the breast piece 30, the spoke engaging member havingfirst been detached therefrom. The drill, when used in such manner, isprovided with a brace 31 attached to the side of the section, as shown.The remaining pivotal suspension of the latter parts of the constructionshown in Fig. 5 are identical with those shown in the first describedconstruction, and are designated by corresponding primed numerals.

\Vhile the device has been described as a drill, it is obvious that abolt wrench may be substituted for a drill and the bolts thus tightenedin the bolt holes.

From the foregoing, it will be seen that my machine is portable; thatis, that it is not suspended from or secured to a wall or post, but-isof such proportions that it may be readily carried from one place toanother.

What is claimed, is:-

A machine of the type set forth comprising a frame provided with a reardepending portion and a front depending portion, a tool shank rotatablymounted in said rear depending portion, and provided at one end with asocket for an operating tool, and at the other end with a member adaptedto engage the under side of the article to be operated upon, a bracedepending from said frame forwardly of said member, and adapted toengage the upper side of the article to be operated upon, an operatingtool in said socket, means for rotating said tool shank,

ears pivotally depending from said front depending member, and pliersincluding crossed pivoted members terminating in gripping jaws, theuppermost of said members being pivoted to said ears at a pointforwardly of its pivotal connection with the lowermost of said members.

In testimony whereof, I aflix my signature, in presence of twoWitnesses.
